IMPROVEMENT IN CARBU RETERS.

Specification forming part of Letters Patent No.

177,104, dated May9,1876; application filed J anuary 22, 1876.

To all whom it may concern Be it known that we, WILLIAM S. DEEDS and GEORGE H. DEEDS, residents of the city of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invented a new and useful Im provement in Air-Gas Machines, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

Our invention consists in the combination, in an air-gas machine, of a certaincompound lever having a spring attachment, with a'throttle-valve for controlling the admission of water under pressure to a water-wheel in such a manner that the opening and closing of the throttle to admit the water to the" wheel and govern its operation, and the operation 'of an air-forcing pump connected with it, shall be regulated automatically by a floating gas-holder, by its upward and downward movementsin the water-tank, by means of certain adjustable tappets on a guidingrod attached to the holder, by means of the tappets pushing against and operating the said levers, by which means the said spring is operated in such a manner as to open or close the throttle instantaneously with the arrival of the floating holder at givenpoints in its travels upward and downward when the gas is being drawn either rapidly or slowly from the holder, by which means the operation of manufacturing the gas shall be performed by water-power automatically,

according to the consumption of the gas at the places to be lighted.

Our improvement also consists in the.

arrangement of a certain check-valve, whereby the hydrocarbonvapor is prevented escap- 'ing out through the air and liquid pipes, all as hereinafter described.

Figure 1 is a perspective view of an air-gas machine, having our improvements combined therewith. Fig. 2 is an elevation of a portion of the airand liquid pipes, having the checkvalve connected therewith. Fig. 3 is an elevation of the same, showing the valve open.

Like letters of reference indicate the same parts mall the figures.

A represents a water-tank, in

which is afloat,

B, having an arm or rod, 0, upon which are adjustable tappets D and D having thumbscrews a and: a for securing the tappets in the proper positions on the rod 0. Thearm or rod 0 passes through an orifice, b, in a support, E, upon whichis hung or hinged, by means ofa pin, a, combined curved levers d and d arranged on different horizontal planes, the one above the other, and attached to a stem, F, having a spring attachment, H, to which is attached a rod, 1, having a slot, 0. The support Ehas a pin attachment, f, which arrests the motion of the spring H,'when the stem F is rocked uponthe pin 0, by means of the tappets D and D pushing against the levers d and d when the gas holder or float B moves upward or downward in the tank A, whereby the said spring H is caused to bend and shortn,'in order to pass the pin f at a given point in the :travel of the holder B upward or downward, at which point the spring H shall fly from the one side of the pin f to the other side, and by assuming its straightened position carry the red I upward or downward, according to the upward or downward motion of the float B, whereby a crank, h, of a water-valve, J, is operated by the spring'H, by means of the crank h, having a pin-connection, c, which' passes through the slot 6 of the rod I. The slot 12 operates to prevent the rod I pulling against the pin 1 and operating the crank while the spring H is bending and preparing to fly from the pin 7', the slot being arranged to slide'over the pin of the crank while the'spring is bending, in such a manner that the pin shall reach the end of the slot at the same time that the spring is prepared to fly, so that the valve J, which is arranged to govern the admission of water under pressure to a water-wheel, K, shall be reversed instantaneously with the arrival of the float B at a given point iiiits upward or downward travels in the ta'nkAI The said water-wheel K is connected,by means of a balance-wheel, j, and rod is, with'an oscillating air-pump, L, having ahose attachment, 1, which may be connected with an airheater (not shown in the draw'ings,) by which means the pump L shall receive warm airand discharge the-san1e,-by means of a hose attach- 6.
